Is Bespin a gas giant?
I thought it was just rich in a gas that was mined there.
It’s certainly got a breathable atmosphere (unless there is some sort of protective bubble around the city.
From StarWars.com:
An immense gas giant surrounded by a number of moons, the planet contains a band of habitable atmosphere among its endless clouds. In this stratum of life, enterprising prospectors have established floating mining complexes devoted to extracting valuable gasses from deep within the planet. The most well known of these ventures is the opulent Cloud City, formerly under the administration of Lando Calrissian. During the tail end of the Galactic Civil War, the Empire garrisoned Bespin and took over Cloud City, though the outpost and the planet enjoyed freedom after the defeat of the Emperor at the Battle of Endor.
